How to create a transfer option for a saw
Set up an entry for the CADmatic saw in the Saw Transfer parameters list. At the main screen:-
• Select: Parameters - Saw Transfer parameters
There is one row for each saw or transfer type.
Saw Transfer parameters

CADmatic 4 |
n:\sawdata\ |
6 - Homag/Holzma CADmatic 3/4/5 |

The items to set are:-
Name - a description or name for the transfer mode
Mode - choose from the following list
3 - Homag/Holzma CADmatic 1
4 - Homag/Holzma CADmatic 2, Micromatic+, Selco CRLINK
5 - CADmatic 2 (with feedback)
6 - CADmatic 3/4/5
Path - any directory. This is the directory where the data is stored waiting for transfer to the saw. The 'transfer program' is called automatically and this transfers the data from 'path for saw data' to the saw. If the 'Path for saw data' is blank no data is transferred. For some links this speeds up the link as the transfer program can take the data directly from the data directory.
For CADmatic 3/4/5 the transfer is via a network. In this mode the CADmatic controller has direct access to the 'Path for saw data' and no additional transfer is needed. In this case the contents of the 'Path for saw data' are not deleted before each transfer as they are in modes 3, 4 and 5.
Program name - enter the name provided by the supplier. For transfer mode 6 there is usually no need to enter the program name as the transfer is via a network.
At the right hand side of the row are a set of extra parameters, for example, to select buffered transfer or select the Cadmatic controller type.
Saw parameters
For any saw parameter list used for transfer via a CADmatic link also set the correct saw model number; this must be one of the numbers for a CADmatic controller.
21 - single saw
22 - angular saw
23 - 3 saw system
24 - 3 saw system with offset head saw
25 - angular saw with turntable at rip saw
Notes
CADmatic 3 part pictures, grooves and cut-outs - The CADmatic 3 controller includes options to groove individual parts, produce cut-out sections, and print pictures of the finished parts. To pass this data to the saw set include options '5' and '6' in the System parameter: 'Create data for'. Grooving and cut-out machine instructions (entered in the part library) must be specified for tool 'T=CAD' in order to be routed to the CADmatic. These instructions are not passed to other machining centres.
CADmatic 3 waste - Where waste at the front of the board or strip exceeds the size of the waste flap some saws can make extra cuts to ensure that the waste is small enough to fall through the trap. For CADmatic 3 (transfer mode 6) the extra cuts are automatically included in the pattern printouts and calculated cutting times. For details refer to the Saw parameters.
CADmatic 3 transfer - program creates a single file for each run in the 'Path for saw data'. The file is named: run_number.saw, for example: 00032.SAW.
CADmatic 1 transfer - For transfer mode 3 the data is automatically converted to the correct format as the data is transferred to the 'Path for saw data'. There are some restrictions on the use of CADmatic 1 format such as the number of materials in a part list and the number of items in a part list - the program reports any errors.
Program name (modes 3 and 5) - if a transfer program name is not set the data is transferred to the 'Path for saw data' (see System parameters)
Unlimited recuts and CADmatic recursive format - some CADmatic 3 (and later) controllers accept the recursive pattern description format (PTNR).
The default is to create the non recursive format (PTN3). In this mode, if a run containing recuts more complex than multiple-uneven is transferred to the saw, a warning message is displayed similar to the following.
Run: 00004 Pattern: 416
Data not correct - pattern has illegal recuts
The recuts which are too complex are omitted from the pattern.
